The degradation of the warfare agent sulfur Mustard (HD) adsorbed onto KIF/Al2O3 sorbents is described. These processes were explored by MAS NMR. using C-13-labeled sulfur mustard (HD*) and LC-MS techniques. Out study on the detoxification of this blister agent showed the formation of nontoxic substitution and less-toxic elimination products (t(1/2) = 3.5-355 h) Interestingly, the reaction rates Were found to be affected by MAS conditions, i.e., by a centrifugation effect. The products and the mechanisms of these processes tire discussed.
